Issues : Authentic corrections of FE

b. 1

composition: Op. 25 No 7, Etude in C♯ minor

..

In GC (→GE1) and EE there is no  returning f at the beginning of the 2nd group of semiquavers of the introduction, which almost certainly corresponds to the notation of [A]. It is a very typical mistake of Chopin – cf., e.g., the Nocturne in Cminor, Op. 27 No. 1, bar 83, or the Impromptu in A major, Op. 29, bar 71. The sign was added in the proofreading of FE, most probably by Chopin, as well as in GE2 (→GE3).

b. 4

composition: Op. 25 No 7, Etude in C♯ minor

No mark in GC (→GE) & EE

Long accent in FE

..

The exclusive presence of the accent in FE suggests that it was added by Chopin in the proofreading of this edition (or still in the handwritten base text). The length of the accent is indicated by its placement to the right from the note. Similarly in bar 8, where the sign is not only moved, but also longer.

Literal reading of slurs in GC (→GE1)

Possible interpretation of slurs in GC, and slur in FE & GE2 (→GE3)

Slurs in EE

..

The slurring of EE is the original state, corrected by Chopin at the stage of manuscripts only in GC. The accurate sense of this correction is not clear (GE1 interpreted the slurs literally as non-connected), yet Chopin proofreading of FE dissipates the doubts concerning the composer's intention. Cf. analogous bars 50-51.

Dotted rhythm in GC (→GE) & EE

Even semiquavers in FE

..

The authenticity of the dotted rhythm in GC (→GE) and EE does not raise any doubts. The equal semiquavers of FE may be considered as a result of inattention of the engraver or misunderstanding of the handwritten base text, yet the version can be also a result of Chopin's correction, introduced still in the manuscript or proofreading of FE. As one of the traces of possible changes performed in print, one can consider the too long slur, adjusted to the note being closer to the bar line than the visible g semiquaver.
